BPSC (Bihar PCS) 2025 · Question 72 of 145

The potential energy of a freely falling body continuously decreases. This is due to which of the following principles?

General Science

  1. AThe principle of conservation of energy is not violatedCorrect
  2. BThe principle of conservation of energy is violated
  3. CGravitational force is violated
  4. DGravitational force is not violated

Answer: A. The principle of conservation of energy is not violated

Explanation

The potential energy of a freely falling body decreases as it is converted into kinetic energy due to gravity. This process does not violate the principle of conservation of energy, as the total mechanical energy (potential + kinetic) remains constant, assuming no air resistance or other external forces.
